This Nationally Adopted International Standard specifies in detail a laboratory method for determiningand reporting the airborne noise emissions of small air-moving devices used primarily for coolingelectronic equipment, such as computer and business equipment. To provide compatibility withmeasurements of noise emitted by such equipment, this Nationally Adopted International Standarduses the noise emission descriptors and sound power measurement methods of ANSI S12.10-2002/ISO 7779:1999. The descriptor of overall noise emission of the air-moving device under test isthe A-weighted sound power level. The one-third-octave-band sound power level is the detaileddescriptor of the noise emission. Octave band sound power levels may be provided in addition to theone-third-octave-band sound power levels. ANSI S12.11-2003 Part 2 describes measurement ofstructure-borne noise generated by air-moving devices.
